BIRD(鸟牌)bird4391A|4391A通过式功率计 PEP-Dual Element, Power Analyst The Model 4391A is a Rugged RF Power Analyst that monitors Peak Pulse Power, Peak Envelope Power, or CW Power during normal equipment operations in the forward or reflected direction. Designed for air navigational aids DME, ATC and other pulsed RF systems such as telemetry, radar, command and control, etc. They need no attenuators, directional couplers or charts. 1.Frequency: 0.45 - 2700 MHz. Power: 100 Mw – 10 kW 2.Reads forward and reflected CW or FM power in watts or dBm, Peak Envelope Power of SSB/DSB and 3.symmetrical AM in watts 4.Calculates SWR, return loss in dB and 5 modulation 5.Shock-resistant keyboard and range switches. RFI protection. Buitl-in international power supply/charger
